There are many operating systems - read about
some (not all) of them here:
� www.operatingsystems.net/
2 main operating systems types to learn:
� Windows and
� Unix

It is easy to hate Windows:

In order to start hating Unix you should read "Unix-haters handbook"
by Simson Garfinkel et al, ISBN 1-56884-203-1, IDG Books, $16.59, out of
print. This book is real fun to read, but difficult to find.
Here are some related links:

There is a constantly updated diagram showing which OSs sucks - and
which rules:

Similar graph is available to compare programming languages:

I also recommend very educational and entertaining reading on this
famous site: Web Tools Review:

The minimal Unix can fit on one floppy disk (1.44 MB) - its kernel is
small and very reliable (if used without X-windows, of course). MS
Windows, on the contrary, takes the order of 100s MB, leaks memory, periodically
dies on you. Thus, although I like Windows-2000 as a work-station, I would
not recommend it as a production server. Unix will be a much better choice
(more reliable, scalable, etc.).

Apple has its own "Mac OS X" based
on Unix (inherited from Steve Job's Next-station's OS).
